Secretary of State George P. Shultz gave his approval today to efforts to isolate Vietnam politically and economically as well as to support the anti-Vietnamese guerrilla warfare in occupied Cambodia.

At a news conference following a round of meetings with U.S. ambassadors stationed in East Asia, Shultz said the Vietnamese had "isolated themselves" from the world by continuing their occupation of Cambodia. He called the Vietnamese role in the neighboring country "outside the pale."

On other issues, Shultz said he was impressed with the importance of taking Asian views into account in U.S.-Soviet negotiations over arms control in Europe.

At several stops during his 12-day Asian tour, according to Shultz, Asians expressed their concern about any arms control settlement that would permit the Soviet Union to transfer nuclear missiles from Europe to Asia.

"It certainly reinforced the virtues of the 'zero option,' " he said, referring to the Reagan administration proposal that calls for the complete destruction of Soviet land-based medium-range missiles in both Europe and Asia.

At the same time, Shultz once again avoided a commitment not to depart from the "zero option." He said the Asians are "not telling us what we should do" in the missiles negotiations.

Shultz visited Japan, China and South Korea before arriving Tuesday in Hong Kong, the British crown colony whose future status is under discussion with Peking. He leaves for Washington Thursday.

The secretary of state expressed optimism that eventually a satisfactory arrangement will be worked out with China to protect this city's stability and prosperity. "It a good thing everybody has going here, and usually people like to keep a good thing going," he said.

The Associated Press added:

Shultz said that there is little hope of stopping Congress from erecting tough trade barriers if Asian nations use protectionist measures to seal their markets to American exports.

He said that it is not enough for Asian nations to express concern about protectionist sentiments in the United States, where many industries feel pressured by imports.

"They need to look in the mirror and see what their own policies are and whether or not they should do something about them," Shultz said.
